Be Ait known that. I, Lorain W.l YOUNG, a citizenr of the United States, residing at New Yorlnin' the county ofNew York aiid State of New York, havey invented certain new and useful linproveinents'in invisible Lighting Units, of which the following aspecification.

This invention relates to ,lamp supports and retlectors, particularly serviceable or an# tended torv what is ltnowii as indirect light'-v inggin which the lalnps are concealed, and the lightdistributed by.l rellection troni an appropriate surface. I I

The object of the invention is to provide aniinprored lixtureland reliec'tor, `as more fully pointed .out hereinafter. Ordinarily,

' Jthe ceiling 4orwall of a rooni is utilized as v1 is a side elevation ofthe device.

is a top plan view, partly broken away, ot

the ietiective'surfaces, andY the lar'nps are-I `disposed above or'belnnd 4projections or Known'A parts so 'that they. are concealed. y holdersA for electricI lainps used insuch systems have the defect that dust eollectsthere'- in, as they areusually disposed in an inv verted position, andthe reflection is neces-.

sari'ly decreased' as vthe dust accumulates. The present invention avoids this defect, thev fixture being -so'constructed that dust will not collect in the holder, and vvthis device alsov provides a glass cover or reflector whichacts to distribute the light in the directiondesired.

ln. the v accompanying drawingsell`igure the `glass"reflector.' Fig. 3 is a cross section oitltigf.

The unit. comprises a trough shaped metal holder 1indicated at 6.",'Tliis is preferably' circular, although itI may be any other shape desired, and it may' be Coated on the inside lin pairs connected by a stein ll'scr'eweo withany suitable reiecting'surface as in-.

dicatedvat 7. This surface may beglass 'or rellecting composition.` The fixture may be supliorted by chains 8 from 'a ceiling bloei@ 9 or the like, the chains being hooked to eyes 10 on the outerA rini of the holder. 'The lamp sockets ll are conveniently arrangedinto the rim and .so arranged thatI the lamps will be located within the trough and coir cealed thereby. At the top the run ot the trough has an inwardly 'projecting flange lll onnvhich rest-s a glass top relector il, which is preferably doine shaped. 'l he rsrious parts inay be ornament-ed as desired,

and different glass reflectors may be substim tuted according to the distribution ot light' desired.

ulnght received by ther glass reectoreither directly troni the lamps or by rellectiou':

:trein the interior of the trough is 'reflected downwardly through the center of the annular holder, and thus will be distributed or vreflected downwardly tir-outwardly over au area depending on the sha-pe of the parts. liiasui-uch as. the unit. is closed at the top, dust will not tend to collect in the trough. Sonie of the light will pass through` the top reflector andl be. di. the proportion of light'refiected und light transmitted may be varied: by- 'iinown modi- `tications of the The unitwill be free troni the objections incident to the collection of dirt above referred to, may be highly 'ornamental in appearance, and has the additional advantage, over ceiling rettection,l vthat the light may be distributed as desired.

I elaine: l

i. il. lighting fixture comprising a traine having a tron-t opening, lamp holders suoported on the vtraine, and mooinbined light reflector and transmitter vmounted on ythe 'traine and extending across the saine, behind the lan'lpy holders, in positioir to re'liect light forwardl through said opening, and to transmit lig itrearwardly. v

j Q.' A lighting lixture comprising a trough shaped traine having a central opening, 5

lainp holders supported' within 'the trough of the traine, the inner ri'ni of the trough projecting rearwardly'wound said opeuing, .so that the lamps will be out 'otsight through saidopening, and a. reflector tending across the traine, behind the opening therein', and arranged to reflect light 'troni the lamps thro-ugh said oper A l'ghting fixture comprising trough shaped traine having an inner 'retiective surface and a central opening, lainpv holders supported in the trough of the traine, andv tributed upwardly, and' lGFi fixture compnsing a' elianrame with a central opening,

' laxnpholders fastened to said frame and adaptedjto-vhold lamps in the channel, said frame having an linner reflecting surface,

and a glass cover resting on the-outer rim -of the frame and extending acrossthe `same behind thelamps and the opening and adapted to transmit light rearwardlm and also toreect light forwardly' through said -cental ope11"ing. y
